So for this tournament every time you get a capture you get one extra move for your next round tell me if anyone broke rules and I will disqualify them.For example he has a group with four liberties it isn’t a capture. \nSo maybe there will be some interesting strategies here and there . This might be a bit boring (sorry) but rules are rules and rules are important.Maybe I am sleeping or something else that will make me not online and someone cheated and it is the last few games in this tournament, just pause or not make a move like or vacation as it is allowed",
